Connectivity
Staying Connected in the DR
Three local carriers, two global eSIM services, and your existing US plan. Here's which combination wins for which traveller — and which spots in the DR have no signal at all.
For most tourists, the practical question isn't “will my phone work?” (it will) but “how do I get usable data without paying US$10/day in roaming?”. The DR has three competing mobile carriers, a healthy eSIM market, and decent WiFi at most resorts — so the right answer depends on trip length, US carrier, and how much driving around you plan.
Local Carrier · The Default
Claro
Coverage: The widest network in the country — cities, resort towns, mountain interior, fishing villages. If anywhere has signal, Claro probably does.
Tourist prepaid: Typical “Plan Turista” offers 30 days, unlimited data, free calls and SMS within the DR for roughly RD$1,500–2,000 (US$25–35).
Where to buy: Claro counters in the arrival halls at SDQ, PUJ, POP, and STI. Also at any Claro retail store and many large supermarkets.
✓ Pros: Best coverage by a wide margin. 4G LTE throughout populated areas, partial 5G in Santo Domingo and Santiago. Airport activation takes 5–10 minutes with your passport.
✗ Cons: Most expensive of the three local carriers. App is Spanish-only by default. Top-up cards (recargas) confuse first-timers.
The safe default. If you want one local SIM that works everywhere, buy Claro at the airport. Done in ten minutes.
Local Carrier · Second Place
Altice
Coverage: Strong in cities and the Punta Cana / Santo Domingo / Santiago corridor. Weaker in mountain interior and the western frontier.
Tourist prepaid: 30-day visitor plans roughly RD$1,200–1,800 with unlimited or high-cap data, free national calls.
✓ Pros: Often the fastest data speeds in tourist hotspots (Bavaro, Zona Colonial, Santiago centre). Cheaper than Claro for equivalent allowance.
✗ Cons: Coverage drops fast outside cities and major resort zones. Mountain trips (Constanza, Jarabacoa) hit dead zones quickly.
Local Carrier · Budget
Viva
Coverage: Major cities and primary resort areas only.
Tourist prepaid: Cheapest of the three — entry plans around RD$700–1,000.
✓ Pros: Lowest cost for a basic data SIM. Fine if you'll only be in Santo Domingo, Punta Cana, or Puerto Plata.
✗ Cons: Coverage gaps are real — you'll lose signal driving the coast or in inland villages. Limited retail footprint outside cities.
Buying Local · The Process
Prepaid SIM Purchase Process
What you need: Your passport (legally required for SIM registration), an unlocked phone, and roughly US$30 in cash or card.
Where: The Claro and Altice kiosks immediately past customs at SDQ and PUJ are the most convenient. Otherwise any branded store in town.
Time: 5–15 minutes including activation and the “please test your data” check by the rep.
✓ Pros: Cheapest data per GB by a wide margin. Local number is handy for restaurant reservations, dive shops, and taxi recall.
✗ Cons: Requires an unlocked phone — locked iPhones from US carriers (especially Verizon-locked devices) will refuse the SIM. The airport kiosk staff don't always speak English.
Confirm your phone is unlocked before you fly. Your carrier can usually do this for free if your line is in good standing — do it a week before travel.
eSIM · The Convenient Option
Airalo
What it is: A global eSIM marketplace — buy and install a DR data plan over the air from your phone before you even land.
Cost: Roughly US$5 for 1 GB / 7 days, US$15 for 5 GB / 30 days, US$26 for 20 GB / 30 days.
Underlying network: Routes via Claro in the DR — same physical coverage.
✓ Pros: Install before you fly. No airport kiosk, no passport scan, no Spanish negotiation. Pay in USD with a foreign card.
✗ Cons: Data-only — no local phone number, no SMS, no voice calls. More expensive per GB than a local SIM. Some 2-factor-auth services don't like the foreign IMSI.
eSIM · Unlimited Tier
Holafly
What it is: Spain-based eSIM provider focused on unlimited-data plans.
Cost: Roughly US$20 for 5 days unlimited, US$50 for 15 days unlimited, US$65 for 30 days unlimited.
✓ Pros: Truly unlimited data with no daily cap. Excellent customer support in English. Hotspot/tethering allowed on most plans.
✗ Cons: Most expensive option here. Speeds may be throttled in some regions after heavy use. Still data-only.
If you'll work remotely from the DR for a couple of weeks, Holafly's unlimited tier is the simplest answer. Just be aware of the price.
Roaming · Your US Carrier
T-Mobile
What you get: T-Mobile Magenta, Go5G, and most newer plans include unlimited data and texts in the DR at no extra cost; calls are US$0.25/min.
Data speed: Throttled to 128–256 kbps on basic plans, full speed on Go5G Plus and similar. Even throttled is enough for WhatsApp and basic Google Maps.
✓ Pros: Zero setup. Phone just works the moment you land. Your US number stays active for verifications and family contact.
✗ Cons: Throttled speeds frustrate streaming and large uploads. Calls cost real money.
For a 5–7 day trip, a T-Mobile customer often doesn't need any other connectivity. For longer stays or heavy data use, add an Airalo eSIM in parallel.
Roaming · Your US Carrier
Verizon
What you pay: TravelPass is US$10/day in the DR — same plan, same speeds as home, capped daily.
✓ Pros: Full home-speed data, full call and SMS coverage, only billed on days you use it.
✗ Cons: US$10/day adds up fast — a 10-day trip is US$100 vs US$25 for an equivalent Claro SIM. The 24-hour TravelPass clock starts the moment you use ANY data, including a background app.
Roaming · Your US Carrier
AT&T
What you pay: International Day Pass roughly US$10/day, or include international roaming via AT&T Unlimited Premium PL tiers.
✓ Pros: Reliable, no setup, premium plans get genuine inclusive coverage.
✗ Cons: Day Pass pricing is identical to Verizon's — expensive for longer trips.
WiFi
Resort, Airbnb, and Café WiFi Quality
All-inclusive resorts: Generally strong WiFi in lobby and rooms; pool and beach WiFi varies. Some properties charge for “premium” tier that streaming requires.
Boutique hotels: Usually excellent in common areas, decent in rooms.
Airbnbs: Wildly variable. The DR has frequent neighborhood power blips — a router without a UPS goes down a few times a week. Check recent reviews.
Cafés & restaurants: Most tourist-zone spots offer free WiFi; the password is on the receipt or the wall.
✓ Pros: Free WiFi is genuinely everywhere a tourist might sit down. You can survive with WiFi-only if your trip is resort-bound.
✗ Cons: Speed and reliability are inconsistent. Public WiFi shouldn't be trusted for banking; use a VPN.
Where You'll Have No Signal
The DR is broadly well-covered, but a few spots reliably go dark even on Claro:
- Los Haitises National Park — mangrove channels, almost no signal once you're past the launch.
- Saona Island — partial signal in Mano Juan village, nothing on the boat ride or at Piscina Natural.
- Cotubaná National Park interior — expect dead zones.
- The Cordillera Central — Pico Duarte hike, much of Constanza, parts of Jarabacoa.
- Bahia de las Águilas — the road in is patchy; the beach itself often has no signal.
- Offshore on most catamaran trips beyond 1–2 km from land.
For any of the above, download offline maps in Google Maps or maps.me before you go, screenshot any addresses you need, and tell someone on land your rough plan.
